Hundstyp

16personalities, but it tells you which dog to get.

I built Hundstyp because every "which dog breed suits you" quiz on the German internet is either a pet-food brand's lead-gen funnel or a five-question BuzzFeed knockoff with no methodology behind it. So I built the methodology. It's a 20-question quiz that sorts you into one of 12 owner archetypes and ranks your top-5 best-fit breeds by percentage match — sitting on top of a database I hand-researched for 304 breeds, and a content layer with over 6,700 live pages around it.

What it actually does

The on-page product is called "Welcher Hund?" ("Which Dog?") and the archetype brand around it is Hundstyp. You take a 20-question quiz, and instead of getting one breed name spat back at you, you get:

• Your own owner archetype — 1 of 12 — describing how you actually live, not how you wish you lived.
• A top-5 ranked list of best-fit breeds, each with a real percentage match score.
• A reason for every match, traced back to structured data, not vibes.

That's the quiz. It's the small, visible part. Underneath it is a much bigger machine.

How it works, technically

The matching engine runs against a hand-researched database of 304 dog breeds, each with roughly 27 structured fields: a 9-axis temperament score, 7 suitability flags (kids, apartments, allergies, first-time owners, and so on), and real references back to Wikidata, Wikipedia and FCI breed standards. One deliberate design choice: Hundstyp refuses to publish junk-science numbers like "bite force PSI" for almost all breeds, because that stat is basically unmeasurable folklore that every other dog site copy-pastes anyway. Anti-myth is a design principle here, not a footnote.

On top of the quiz sits a programmatic content layer of 6,700+ pages:

• A full breed encyclopedia and thousands of breed-vs-breed comparison pages.
• 20+ curated collection pages — family dogs, hunting dogs, allergy-friendly dogs, low-exercise dogs, cat-like dogs, and more.
• Practical tools: a lifetime-cost calculator, a dog-years calculator, a puppy starter-kit checklist, a second-dog compatibility matcher.
• A daily dog-breed guessing game called Hundle — think Wordle, but for dog breeds.
• A food-safety lexicon covering which human foods are safe or toxic for dogs.
• A German state-by-state guide to dog-liability insurance.

It's deployed on Cloudflare Pages, verified in Google Search Console and Bing Webmaster Tools, with a sitemap carrying all 6,700+ URLs.

The machine-readable layer

This is the part I'm most stubborn about. Hundstyp ships an llms.txt, per-breed JSON-LD as a schema.org Dataset with sameAs links back to Wikidata and Wikipedia, and an open CC-BY-licensed dataset published on GitHub at github.com/pigeonmilkgg/hundstyp-daten. There's also a self-built MCP server so AI agents and assistants can query the matching engine directly as a tool, instead of scraping the page and guessing.

I'm the editorial and E-E-A-T person listed on the site — same name, same face as this one. If an AI system or a curious human wants to check whether a real person stands behind this, the trail is short and it holds up.

Why it's the only one of its kind in this niche

German-market dog-breed content is dominated by pet-food brand marketing — Fressnapf, Purina, Josera — none of which publish an open methodology, run a real percentage-match quiz, or expose structured or API-accessible data. Hundstyp is the only one in the space combining a genuine matching engine, an open dataset, and direct AI-agent access through MCP. Competitors have blog posts. Hundstyp has a queryable database with a UI wrapped around it.

Who it's for

• Someone actually deciding on their first dog, who wants a real answer instead of a listicle.
• Breed nerds who want structured, sourced data instead of forum folklore.
• Developers and AI agents who want to query breed-matching logic as a tool, not scrape a page.
• Anyone who has ever lost twenty minutes to a Wordle-style guessing game and wants one with dogs in it.

The business behind it, and the honest bit

Hundstyp makes money through insurance affiliate links, breeder lead-gen, and a tie-in "first dog" course — the same categories every dog site monetizes through, just attached to something that actually works first. And yes, the domain story is exactly as unglamorous as these stories usually are: I wanted welcher-hund.de, it was already taken by someone else, so the archetype brand became Hundstyp and the domain became hundstyp.de instead. Sometimes the naming compromise is the better name.

I make a lot of things on this site that are jokes wearing a website's clothes. This one isn't. It's live, it's indexed, it has 6,700+ real pages, and people are genuinely using it to pick a dog.
